Abstract: The present invention provides for a process for synthesis of carbon beads comprising sub-micron size, micron size or milli size. The process enables modulation of the viscous slurry for synthesis of the carbon beads with improved physico-chemical properties. The process enhances ability of the carbon beads to withstand extreme pH and high temperatures. The present invention also provides a composition for synthesis of the carbon beads. The present invention also provides a microfluidic droplet generator for synthesizing the carbon beads. The carbon beads synthesized by the present invention are applicable in separation, filtration, purification, wires and cables, electrodes, sensor, composite and additive manufacturing, pharmaceutical delivery applications.

Abstract: A system for detecting an arcing fault in a telephone central office DC power distribution conductor repeatedly measures the current flow in the distribution line, as with an inductive coupling, and derives a Fourier transform analysis spectrum from such measurements. The power values at intervals across the frequency spectrum are compared with recorded threshold template values encompassing the spectrum typical of an arcing event and an alarm condition is established when such threshold levels are exceeded.

Abstract: An ornamental necklace made up of annular members in combination with beadlike elements wherein the annular members are disposed in alternating overlapping relation together with stringing means or the like for maintaining the annular members in their overlapping relation; the beadlike elements being disposed within and/or between successive annular members in the stringing means and concealing such stringing means, the relationship of the beadlike elements and the annular members being such that the necklace may be worn to expose either side thereof to thereby provide alternative ornamental effects.
